SPRINGFIELD -- Public and private investment in the city since the tornado of June 2011 now totals more than $3.76 billion, Chief Development Officer Kevin Kennedy said Tuesday during a presentation at CityStage.

Kennedy gave an economic development update to the Springfield Regional Chamber of Commerce at his "The New Springfield: Now Arriving" program. The $3.76 billion number is up $453 million since Kennedy's most recent CityStage update in November 2016.

The total value of projects since 2011 includes a few once-in-a-lifetime developments like the $960 million MGM Springfield casino, the $95 million it cost to renovate Union Station and the $95 million CRRC rail car factory in East Springfield.

Such development might make it hard for Springfield to keep up the momentum with Union Station open, CRRC set to start making rail cars for the MBTA next month and the casino on track for a September opening.

But completed projects doesn't mean the city stops looking for new ones to start.

For now, spin-offs from companies like CRRC and downtown businesses taking advantage of the crowds drawn by MGM or passengers streaming through Union Station will likely be the next steps in Springfield's redevelopment.

Projects like a planned $6.9 million refresh of Main Street, a pedestrian wayfinding system of interactive kiosks and the new Valley Bike bikeshare are designed to get people downtown.

Michael Mathis, president and COO of MGM Springfield, said the casino's next step is "mass hiring" -- onboarding big groups of new employees as the casino climbs to its expected headcount of about 3,000.

The slot machines are starting to arrive, he said, and the casino floor is starting to look like a casino floor.

Kennedy singled out Jay Ash, state secretary of Housing and Economic Development, and the administration of Gov. Charlie Baker for their help. Ash helped convince MassMutual to move 1,500 jobs here rather than to another state. His department has also provided funding for projects like the planned $3.5-million rehab of Pynchon Park.

Ash, a featured speaker at the event, said the state's ability to keep on helping out rests on the success of Baker's proposed $610 million economic development bill.

It's no coincidence that Baker unveiled the bill earlier this month at another Springfield chamber event.

"What you are doing is everything that should be done," Ash said. "We are happy to continue to support the vision that is here."

The bill includes $300 million for the MassWorks Infrastructure program cities like Springfield can use for roads, sewer, water or, increasingly important, internet connectivity required to attract businesses.

Kennedy also explained public safety improvements like the new police substation that will be part of Pynchon Park. There also will be a dedicated downtown police unit with 41 officers and supervisors, new equipment and more surveillance.

The cost is $1.5 million a year.

"It will be a safer city because we won't be pulling police out of the neighborhoods to respond to calls downtown," Kennedy said.
